Mtdpart doesn't free pparts when a cleanup function is declared.
Add missing free for pparts in cleanup function for smem to fix the
leak.

In the event of a skipped partition (case when the entry name is empty)
the kernel panics in the cleanup function as the name entry is NULL.
Rework the parser logic by first checking the real partition number and
then allocate the space and set the data for the valid partitions.
The logic was also fundamentally wrong as with a skipped partition, the
parts number returned was incorrect by not decreasing it for the skipped
partitions.

Its possible for the main smem driver to not be loaded by the time we come
along to parse the smem partition description but, this is a perfectly
normal thing.
No need to print out an error message in this case.

Add cleanup function as the name variable for the partition name was
allocaed but never freed after the use as the add mtd function
duplicate the name and free the pparts struct as the partition name is
assumed to be static.
The leak was found using kmemleak.

Partition size and offset value are in block size units, which is the
same as 'erasesize'. But when 4K sectors are enabled erasesize is set to
4K. Bail out in that case.

qcom_smem_get() does not return NULL, and even if it did, the NULL
condition is usually not an error but a success condition and should
not trigger an error trace.
Let's replace IS_ERR_OR_NULL() by IS_ERR().
This fixes the following smatch warning:
drivers/mtd/parsers/qcomsmempart.c:109 parse_qcomsmem_part() warn: passing zero to 'PTR_ERR'

NAND based Qualcomm platforms have the partition table populated in the
Shared Memory (SMEM). Hence, add a parser for parsing the partitions
from it.
