mwifiex: Fixing NULL pointer dereference
Following OOPS was seen when booting with card inserted
BUG: unable to handle kernel NULL pointer dereference at 0000004c
IP: [<f8b7718c>] cfg80211_get_drvinfo+0x21/0x115 [cfg80211]
*pde = 00000000
Oops: 0000 [#1] SMP
Modules linked in: iwl3945 iwl_legacy mwifiex_sdio mac80211 11 sdhci_pci sdhci pl2303
'ethtool' on the mwifiex device returned this OOPS as
wiphy_dev() returned NULL.
Adding missing set_wiphy_dev() call to fix the problem.
