[PATCH 1/2] NFC: nfcsim: Staticize local symbols

[PATCH 1/2] NFC: nfcsim: Staticize local symbols

[Jingoo Han]

These local symbols are used only in this file.
Fix the following sparse warnings:

drivers/nfc/nfcsim.c:63:25: warning: symbol 'wq' was not declared. Should it be static?
drivers/nfc/nfcsim.c:484:12: warning: symbol 'nfcsim_init' was not declared. Should it be static?
drivers/nfc/nfcsim.c:525:13: warning: symbol 'nfcsim_exit' was not declared. Should it be static?
