mwifiex: Fix three heap overflow at parsing element in cfg80211_ap_settings

mwifiex_update_vs_ie(),mwifiex_set_uap_rates() and
mwifiex_set_wmm_params() call memcpy() without checking
the destination size.Since the source is given from
user-space, this may trigger a heap buffer overflow.

Fix them by putting the length check before performing memcpy().

This fix addresses CVE-2019-14814,CVE-2019-14815,CVE-2019-14816.

mwifiex: Fix heap overflow in mwifiex_uap_parse_tail_ies()

A few places in mwifiex_uap_parse_tail_ies() perform memcpy()
unconditionally, which may lead to either buffer overflow or read over
boundary.

This patch addresses the issues by checking the read size and the
destination size at each place more properly. Along with the fixes,
the patch cleans up the code slightly by introducing a temporary
variable for the token size, and unifies the error path with the
standard goto statement.

mwifiex: Use accessors routines for unaligned values

Synopsys' ARCompact architecture does not support loading from or
storing values to unaligned memory locations. We saw a series of
misaligned access exceptions on ARC. To work around this issue, we bulk
replaced le16_to_cpu and le32_to_cpu with get_unaligned_le16 and
get_unaligned_le32, respectively. We also added le16_unaligned_add_cpu
which is similar to le16_add_cpu but works with unaligned values.

mwifiex: handle start AP error paths correctly

It's been observed that even if firmware returns an error
for a configuration command, we go ahead and start AP.

This patch changes the command type from async to sync
so that threads waits for command response and return
failure start AP.
